NAME

battery-stats - collected battery statistics

DESCRIPTION

The battery-stats contains statistics about battery charge over time,
as collected by the battery-stats-collector (8) daemon.

FORMAT

Each line in the file represents one sample and is of the form:
<seconds> <charge%> <powermode> <UTC-date> <UTC-time>
separated by spaces and terminated by a newline.
Where:
seconds
is the number of seconds since 1st Jan 1970 00:00:00 UTC
charge%
is the battery charge a number between 0 and 100
powermode
indicates the power mode:
0 A/C off
1 On battery
2 On backup power
UTC-date
a human-readable date in the format YYYY/MM/DD. Note that this
is in UTC, not the local or system timezone.
UTC-time
a human-readable time in the format HH:MM:SS (using a 24-hour
clock). Note that this is in UTC, not the local or system
timezone.
minutes-left
is the BIOS estimate of how many minutes of running time the
battery would provide. This may be unreliable, depending on the
BIOS through which it was collected.

FILES

The default set-up is to save battery statistics in /var/log and rotate
the logs weekly, which results in this set of files:
/var/log/battery-stats - current (most recent) statistics
/var/log/battery-stats.[0-9]+ - less recent statistics
/var/log/battery-stats.[0-9]+.gz - ancient statistics
